HEATING APPARATUS FOR OIL-=TAN KS.

QPECIFICATION forming part of Letters Patent No. 539,912, dated May 28, 1895.

Application filed March 2. 1893. Serial No. 464.333. (Ilo model.)

The object of my invention is to so con-- struct the heating device as to have little or no part of it exposed to the cold outer air and to arrange it so that it may readily stand the strain, thumping and rough treatment to which such cars are subjected.

The drawings which illustrate the invention although applicable to any class of cars are shown as illustrating an oil tank. Now

in the transfer for long distances ofoil in tanks and during cold weather the oilsolidifies and gets very thick and when it arrives at its destination, will not run out of the tank unless there be some means for heating the same to liquefy it to that point at which it will readily pass through a tube. For this purpose various devices have been used but so far as'I know none of them have been satisfactory. In some, the pipes were exposed, in others the apparatus was provided with valves which. subjected to the roughtreatment of train men soon became out of order and the whole apparatus was easily deranged by the more than ordinary strain and severe service placed upon it. My apparatus is intended to remedy this defect.

Figure 1 represents a plan view of the device within an oil-tank; Fig. 2, a side view of the same; Fig. 3, a sectional view taken on the line as so of Fig. 2.

A is a tank for holding oil.

BB are the heating pipes connected with the steam supply through the pipe b. The pipes B-B are joined together by an elbow b at one end, and the steam pipe b enters this elbow about centrally of the elbow and projects up through the top of the car. At this end of the car I place a clamp O constructed substantially as shown in Fig. 3. A flat bar of iron of about three-fourths of an inch in ling screwed onto the end of the pipe which forms a shoulder of one sideof the clamp. The short piece of pipe extending therefrom and connecting with the elbow forms the part which enters the bearing and the elbow itself provided on either side with a coupling or collar forms the shoulders on the other side of the clamp; so that when the pipes with the connecting elbow are inserted in the bearings they are held rigidly and there can be no lateralor longitudinal movement of the pipe. The caps c are then bolted in place sufficiently tight to hold the pipe without breakingit. This arrangement on that end prevents the breakage or straining of the pipe I) and also prevents the straining of the aperture above in the upper part of the tank through which the pipe passes and insures a good joint. I have also placed other clamps D and E of similar construction and similarly attached to the tank. These clamps are provided with bearings and caps but instead of screwing them down tightly, the pipes pass loosely therethrough, andv being without collars or shoulders may have any amount of lateral or longitudinal movement.

It will be seen by this arrangement that the pipes B being rigidly held at one end, the expansion and contraction due to heat and cold may have free play without exerting any strength or creating any damage upon the structure of the device, and all of the pipes being entirely closed within the tank are never subjected to the jamming, pumping and straining incident to the rough railway traffic which they have to encounter.

At the other end of the tank where the clamp E is placed the pipes B--B are joined by the T-pipe F, and as this end of the pipe would be located nearly or quite over the trucks of the car it is extended backwardly 7 I has and passed through the car beyond the trucks. It is also formed in a serpentine or Sshape, so that it may readily yield and give to the expansion and contraction of the pipes B. At its outlet, the aperture in the bottom wall of the tank is reinforced by a piece of metalf on one or both sides, and riveted thereto, and for convenience provided with a screw thread within which is inserted the outlet pipe. It will be seen that this structure will effectually resist any strain or rough treatment to which it may be subjected. The inlet aperture through the upper wall of the tank at the other end through which the pipe 1) passes may also be reinforced in the same way. The ends of both the inlet pipe and the outlet pipe are simply capped or plngged,by the plugs b and 6 without a valve or any other delicate device liable to disarrangement, and are secured by a chain to prevent loss.

Now notwithstanding the fact that a pipe such as hereinabove described may be used, nevertheless in cold climates the steam in such pipe is apt to condense and the water-of condensation freeze 1 herein, or become so cold as not effectually to perform its work, and if the pipes remain open so that the steam may have direct passage thereth rough it would be verydifficult to get them hot enough to effectually heat the oil and renderitsufficiently liquid to run out of the tank, and yet it is desirable not to allow the steam to remain in the tank but to pass it entirely through in a constant flow. I therefore insert within the pipe an earthenware or non-metallic block similar to that used by the Morton Oompanys system and illustrated in the patent to Thomas M. Morton, dated August 2i, 1888, No. 388,065.

The operation of the device is as follows: The tanks arrive at their destination filled with an oil in a congealed or thickened state. The caps or plugs b and e are removed. Steam connection is made with the pipe I) and the steam allowed to pass through the pipes 13. In passing, the brick absorbs the heat, holds and retains it and the steam and water of condensation pass through and out the other end, at all times retaining heat sufficient to liquidize the oil and allow' it to run, while the pipes may expand without strain upon the structure.

WVhat I claim, and desire to secure by Letters Patent, is-

1. In an oil tank, a heating device located wholly within the tank at or near the bottom, consisting of the pipes Bl3 running longitudinally with the tank, and connected with the steam inlet pipe 1;, running through the top of the tank and secured thereto, in combination with supporting brackets for the pipes Bl3, rigidly secured to said pipes at the steam inlet end, whereby said pipes are allowed to expand toward their opposite end and thereby prevent strain or breakage of theconnecting pipe I), substantially as described.

2. In an oil tank, a heating device located wholly within the tank at or near the bottom, consisting of the pipes BB, running longitudinally with the tank, and connected with the steam inlet pipe 7), running through the top of the tank and secured thereto, in combination with supporting brackets at each end of the pipes 13-13, and rigidly secured to the bracket at the steam inlet end with an expan sion outlet pipe running from the end of pipes BB opposite the steam inlet, through the bottom of the tank and secured thereto, substantially as described.

in an oil tank, a heating device located wholly within the tank at or near the bottom, consisting of the pipes l3l3, running longitudinally with the tank, and connected with a steam inlet pipe I), running through the top of the tank and secured thereto, in combination with supporting brackets at each end of the pipes BB, and rigidly secured thereto, at the steam inlet end, and passing loosely through the bracket at the other end, and provided at said end with an expansion pipe running through the bottom of the tank and secured thereto, and having the inlet and outlet pipes provided with plugs, substantially as described.

at. In an oil tank, a heating device located wholly within the tank near the bottom,consisting of the pipes Blrunning longitudinally with the tank, and connected with a steam inlet pipe 19, the pipes BB provided with an inclosed perforated heating brick, in combination with supporting brackets at each end, rigidly secured to the pipes 13-13, at the steam inlet end, and loosely holding the same at the opposite end, and an expansion outlet pipe passing through the bottom of the tank and rigidly secured thereto, substantially as described.

Signed at New York, in the county of New York and State of New York, this 9th day of February, A. D. 1893.
